{"id":"CVE-2026-33501","aliases":["GHSA-96qp-8cmq-jvq8"],"url":"https://o3.security/vulnerability/CVE-2026-33501","summary":"AVideo has Unauthenticated Information Disclosure of User Group Permission Mappings via Permissions Plugin","details":"WWBN AVideo is an open source video platform. In versions up to and including 26.0, the endpoint `plugin/Permissions/View/Users_groups_permissions/list.json.php` lacks any authentication or authorization check, allowing unauthenticated users to retrieve the complete permission matrix mapping user groups to plugins. All sibling endpoints in the same directory (`add.json.php`, `delete.json.php`, `index.php`) properly require `User::isAdmin()`, indicating this is an oversight.
